Update DMPHub sync script for new DMPHub v2

[briri]

We need to move the existing DMP IDs into the new DMPHub v2.

To do this we will start from the DMPTool (our system of Provenance) and do the following:

• Copy the existing rack task and modify to point to the new DMPHub
• Make necessary changes to the app/services/external_apis/dmphub.rb service
• Update the SSM credentials for DMPTool
• Adjust the JSON output to work with the new DMPHub (e.g. move download URL into dmpraodmap_related_identifiers)
• Make sure that the DMPHub provenance record in DMPHub allows for the retention of existing DMP IDs (so it won't mint new ones)
• Run a sample set and then do side-by-side comparisons with DMPHub v1 to ensure that we have fidelity
• Migrate full set of DMP IDs
• Update the SSM credentials for DMPTool to point to the new DMPHub Dev environment
• Update the SSM credentials for DMPTool to point to the new DMPHub Stg environment and disable retention of existing DMP IDs
• Update the SSM credentials for DMPTool to point to the new DMPHub Prd environment and disable retention of existing DMP IDs
• Update contact and contributor in JSON to output name as Last, First
• Exclude the abbreviation from the affiliation JSON info. Make sure all affiliation are dmproadmap_affiliation
